THREAD-CUTTING TEMPLE non. Looms.

Application filed September 11, 1923. Serial Ito. 662,114.

To all whom it may concem:

Be it known that I, l-VALTER C. HUDSON, a citizen of the United States,and a resident of rrndeison, county of Anderson, State of SouthCarolina, have invented an Improvement in Thread-Cutting Temples forLooms, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawingrepresenting like parts.

This invention relates to loom temple constructions in general and moreparticularly to thread cutting temples for looms and the principalobject of the invention is to provide a thread cutting temple havingcutting members which will engage the filling with certainty and severthe same with a shear.- ing cut.

A further object of the invention is to provide a thread cutting templeconstruction in which the rocking and sliding movable cutter is soconstructed that it cannot engage and wear the supporting stud for thetemple roll notwithstanding any wear which may occur upon the rockingand slidingmember oi the ways in which it is mounted.

A further object of the invention is to provide a loom temple with anovel form of slide bar of a more rigid construction than heretoforeproduced.

llhese and other objects and features'of the invention will more fullyappear from the following description and the accompanying drawings andwill be particularly pointed out in'the claims.

In the drawings:

Fig. l is a side elevation of a thread cutting temple for looms of thewell known Dutcher type having the invention embodied therein;

Fig. 2 is a near elevation of the head portion of the temple illustratedin Fig. 1;

Fig. 3 is a transverse sectional view through theslide bar of the loomtemple on line 3-3 Fig. 1;

Fig. 4 is. a side elevation of a different .form of loom templeembodying the invention; and,

Fig. 5 is a rear elevation of the head of the tem le illustrated in Fig.4.

uThe oom' temple construction illustrated ingthe accompanying drawing,comprises a temple stand 1 having suitable ways in which the slide bar2, which supports the temple head, is reciprocably mounted, the slideher being provided with a. shouldered portion 3 which is. normallypressed,hy a

helical spring 4- surrotinding an extension 5 on said slide har, againstthe inner face of the end 6 of .the temple stand 1. The free end of theslide bar 2 is downwardly offset and has formed integral therewith thelower portion 7 of the temple head which includes the usual pod 8. Thehead of the temple'also comprises a. cap 9 which is provided at itsouter portion with an up wardly extending boss 10 which, in the presentinvention, projects upwardly higher than those of usual templeconstructions to provide room for the particular type of rocking andsliding cutting member as will hereinafter more fully appear.

The cap 9 is secured to the temple head by a screw 11 and a lock nut 12in the usual manner.

One of the features of the present invention consists in providing amore rigid slide bar construction than heretofore which will be lesslikely to be broken by the continued heavy shocks produced by theheating up of the lay.

, In the particular construction illustrated the slide bar 2 comprises avertical web 13 provided with integral longitudinally extending ribs l lwhich desirably are of rectangular cross section, said ribs extendingfrom the usual thickened oflset portion forming part of thehead to theshouldered portion 3 whichabuts against the inner face of the end 6 ofthe temple stand. The end portion 6 of the temple stand desirably isprovided with suitable ways to embrace the ribs 1%. By reason of thisconstruction a much more rigid slide bar is produced which will bepractically free from breakage.

The cap 9 of the temple head is provided at its inner and outer endswith the usual downward extensions 15 and 16 in which are mountedrespectively the studs 17 and 18 upon which the toothed temple roll 19is 'rotatably mounted.

The temple head is provided with the. usual downwardly extending heel 20which is engaged by the la upon-its beat-up and through it the temp e isforced forwardly toward the breast beam of the loom against the actionof the spring 4. The temple head presents the usual substantially flatface 21 having at its outer end a V-shaped recess 22 which receives thefilling strand which runs from the salvage of the cloth to the shuttle.In usual thread cutting temples of this type the cutting mechanismcomprises a vertical cutter having an edge which is substantially flushwith the vertical face 21 or which inclines slightly forwardly therefromand a rocking and sliding cutting member having a blade the edge ofwhich extends downwardly and rearwardly with respect to the verticalface 21 during the sliding movement of the cutter after the same hasbeen rocked to sliding position, the object of the rearward inclinationof the cutting edge being to produce a shearing cut. Such rearwardinclination of the edge-of the movable cutting blade has a tendency toforce the filling downwardly and beyond the edeclive portion of theblade.

The principal object of the present invention is to provide co-operatingstationary and movable cutting members of such construction that thefilling will be severed with certainty by a more efi'ective shearingaction. This is accomplished in the present .construction by providingthe vertical stationary cutting blade with an extension presenting adownwardly and rearwardly inclined cutting edge prefe'rabl projectingbeyond the face of the temp e head, the downwardly and rearwardlyextending edge thereby tending to raise the filling as it is engaged bythe movable cutting blade so that the cutters will act upon the samewith greater certainty.

In the construction illustrated herein the stationary cutting member 23consists of a flat steel blade which, is mounted at one side of avertical recess in the head of the temple adjacent to the outer end ofthe toothed roll 19 and held in position by any suitable means. Thestationary cutter comprises an upper portion 24 which extends well upinto the recess in the pod and preferably is provided with an edge 25which inclines forwardly from the face 21 of the temple head. The lowerortion of the stationary cutter 23 is provi ed with an extension 26which presents a downwardly and rearwardly extending edge 27 which,projects beyond the plane of the temple face 21. The rocking and slidingc'o-operating movable cutter may be of the usual type within the broadscope of the present invention.

A further object of the invention is to provide an improved rocking andsliding cutting member so constructed that it will not by anypossibility engage and wear-the supporting stud of the temple rollduring its movement and also to provide the rocking and sliding memberwith a specially de-v signed, preferably duplex, cutter to co-operatewith the stationary cutting blade In the construction illustrated hereinthe rocking and sliding cutting member 28 is reaaeeo mounted in theusual slots in the temple head and is provided with a downwardlyextending heel 29 adapted tobe engaged by the lay upon its beat-up. Therocking member 28 is provided with laterally extending flanges 30 and 31which engage respectively shoulders 32 and 33 upon the forward portionof the temple head. The movable cut ting member is normally held inplace, as illustrated in Fig. 1, by the usual sprin 34 which is coiledat one end about a stud 35 projecting "from the side of the slide bar 14and at its opposite end about a stud 36 which projects'laterally fromthe side of the cutter heel 29. Upon the beat-up of the lay the heel 29is engaged by the lay andas it is forced rearwardly the, cutting member28 is first rocked downwardly about shifting fulcrums produced by thesliding en-.

gagement of the flange 30 with the shoulder 32 and the flange 31 withthe shoulder 33 until the lower horizontal edge 37 of the cutting memberengages the horizontal way 38 in the cutter head after which the cutteris moved bodily rearwardly during the further movement of the lay. ythis construction, therefore, the movable cutter is given first arocking and then a sliding movement.

. The free end of the rocking and sliding member 28 has secured to it orformed integral with it one, or referably duplex cutting blades 39whic'i co-operate with the stationary cutter. lVhere duplex cuttingblades are employed they are located upon opposite sides of thestationary cutter.

. In the present construction the rocking and sliding member desirablyis so constructed as to be tilted to a higher angle with respect to thebase of the temple head than in usual constructions and is provided witha larger and higher recess 40 extending upwardly from the under face 37thereof so that the stud'18, which supports the outer end of the toothedroll, cannot possibly be engaged by the rocking and sliding D1l11 her byreason of any wear which may occur between said member and the supportwith which it engages, or by reason of excessive throw of the cutter dueto the blow of the lay upon the heel 29.

The cutting blades 39, as illustrated in Fig. 1, are preferably soconstructed that their cutting edges l1 will extend in substantialparallelism with the face 21 of the temple head as the rocking andsliding member 28 completes its-rocking movement. By reason of thisconstruction the edge 41 of the cutting blade will sweepdownwardlyaround the filling during its rocking movement and during its slidingmovement will draw the filling against the downwardlv and rearwardlyinclined edge of the portion 26 of the stationary cutting blade whichprojects beyond the face of the temple head so that the filling will bemoved upwardly by the inclined edge 27 as it is drawn against the sameand will be severed with a shearing out. i

It will be noted that in this construction the upward movement of thefilling "causes it to be engaged with certainty between the movable andstationary cutting blades. and the severance thereof is thereby insured.

The invention is illustrated in Figs. 4 and 5 as applied to a'diii'erent form of thread cutting temple of the ty e disclosed in theprior patent to Edward Stimpson, No. 1,366,034 grant-ed January 18,1921, which discloses a thread cutting temple for loomsin which thecutter member is molded of a single; integral piece of castiironcomprising a body and a heel projecting from one edge of the body and achilled cutting blade projecting from another edge of the integral bodywith a cutting edge formed on the chilled portion.

In the construction illustrated in Figs. 4 and 5 the temple head 42preferably is carried by a slide bar 43 having longitudinally extendingstrengthening ribs 44 of the character above described.

In this construction the temple head 42 is provided with the usual pod45, cap 46 and toothed roll 47 mounted upon studs/1:8 .and 49respectively in the manner above described. The stationary cutting blade50 is mounted in alined slots 51 in the base of the temple head and 52in the cap and is secured in place by a screw .53 seated in the cap. Thetemple head is provided with the usual downwardly extending heel 54which is engaged by the lay upon, its beat-up. The movable cuttingmember isof the rocking and sliding type comprising a body 55 of castmetal having an integral heel 56 projecting downwardly therefrom andlaterally extending flanges 57 and 58 normally held against shoulders 59and 60 respectively by a spring 61 which is mounted at its upper endupon a stud 62 projecting laterally from the slide bar 44 and wound atits lower end upon a stud 63 projecting laterally from the heel-56. Thebody 55,01 the sliding member is provided with an ;integral cuttingportion 64. which,

as illustrated in Fig. 4, has a downwardly and rearwardly extendingcutting edge 65 the blade portion of the member .65 being chilledto-presenta hardened cutting blade. The body of the member 55 isprovided with a recess 66 of sufiicient depth to avoid possibility ofengagement with the stud 49 of the temple roll as heretofore stated.

The stationary cutting blade 51 in this construction is provided with alower portion 67 which dprojects beyond the face of the temple hea andpresents a downwardly and rearwardly extendin cutting edge 68 with whichthe edge 65 0% the movable cutting blade co-operates in the mannerheretofore described.

, tightly closed in the prior In this construction, as in thatillustrated in Fig. 1, the inclination of the edge of the stationarycutting blade tends to raise the filling into the bite of the cuttersand to insure the severance of the filling.

In the construction illustrated in Figs; i and 5 the movable cuttingblade 6-l is held against the stationary cutter by a plate 69 which ismounted in a suitable slot in'the cap and retained therein by the screw53. A screw '70, which ismounted in the end of the cap, engages the sideof the plate 69 and provides mfeans for adjusting the plate laterally insuch a manner as to "pro duce proper eo-operation between the edge- 65of the movable cutter and the stationary cutter. A look nut 71 upon thescrew '70 serves to retain it in adjusted position. The adjustment or"the plate 69 is, however, disforms no part of the present invention.

By reason of the construction heretofore patent to Stimpson and vdescribed, therefore, it will be seen that the I supporting the templehead and also pro-- vides means for more certainly and effectivelysevering the ,tillingand also includes means for preventing the rockingand reciprocating cutting member from engaging and wearing the studwhich supports the temple roll.

It will be understood that the embodiment of the invention disclosedherein is of an illustrative character and is not restrictive and thatvarious modifications in form, construction and arrangement of parts maybe made within the spirit and scope of the following claims. 1 7 Havingthusdescribed-the invention, what is claimed as new, and desired to besecured by Letters Patent, is:
